One issue was that there was no way to use PWA to work with the photo's uploaded to a Google+ Page, rather than an individual Google+ profile.
And this was highlighted when Google introduced an auto-enhancement feature which could be disabled using Picasa-web-albums, but not using Google+ Photos.
However a new feature introduced to Google+ Pages means that you can work around this.
How to access Google+ Page photo albums using Picasa-web-albums
Set up a separate password for your Google+ Page..
Log out of Google / Blogger / Picasa-web-albums (if you log out of one, you are generally removed from the others too).
Log back in again, but this time using your newly created Google+ Page account.
Point your web-browser to Picasa-web-albums, using the do-not-re-direct address: https://picasaweb.google.com/lh/myphotos?noredirect=1
Job Done!
You can now use Picasa-web-albums like normal, including access to features like:- Turning off image auto-correction
- The (far nicer) PWA upload features
- Sharing your photos on any website, not just on Google+
And of course you still have access to the Google+ Photos features, like editing pictures without changing their URL.
Disadvantages / Issues
There's always one!In this case, it's that you need to be logged into Google using a different account from the one that's the underlying Page owner. You can use any of the other Google tools (Maps, Blogger, probably even AdSense) - but it will be with the Google account that was created for your page, rather than with your personal account.
And if you manage multiple pages, you will need to think carefully about exactly how each one is set up, and what account you need to use to work with it.
